working or shortly after its working.
Warning:Be care of the low temperature
When using the liquid nitrogen to cutting the
materials ,the user’s hand may hurt by the lower
temperature gas tank .Please wear the gloves when
connecting the gas tank with the machine
Warning: It’s not allowed to open the door ,put your
hands body into the moving area during machine
running process
1.4 Security management warning
a). Specify the security administrator, determine scope of their duties, and
laser processing operator must get safety education and read the use
guide manual.
b). Specify laser safety management area, set up warning card in the
management area’s entrances and exits, content including: power of laser
machine, laser type, not allowed to enter, protect eyes and security manager's
name, etc.
c). Our company would undertake a training activity(face to face or training on
the Internet) to the customer. Operator of laser processing machine, must
receive special training, to reach a certain level, and on the premise of
security administrator agree, then operate the machine.
1.5 Laser safety notice
The laser source of this machine is belong to 4 class laser.The main harm
to human body are the eyes and skin, laser light to any part of the human
body can cause burns.Especially long time watching fiber laser will cause
the retina serious damage to the eyes! Avoid to put any parts of the body
in flight path of laser equipment, in order to avoid damage due to incorrect
operate.

1.6 Eyes and skin’s protection
Caution :When the machine’s door is open in processing.All
operators must be strictly wear 1064 nm laser protective
glasses!(the model can choose SD - 4) Don't wear glasses
for operation and observation prohibited!,
1.7 Fire and high temperature protection
a).Fire protection of laser cutting processing, often use oxygen, and spark
cutting the splash, oxygen is easy to cause the danger of fire. So there should
be no inflammable and explosive articles of the workspace, and the
corresponding prevention facilities. Please close the machine’s door when
processing the materials.
b).Don’t put inflammable materials in the waste bunker.
c).Please put a fire extinguisher in the designated spot. Please refer picture 3-2.
Caution: Must wear protective gloves.
As the laser cutting process will generate a lot of heat please
wear gloves and wait 5-10 minutes after the laser machine stop
working to touch the materials and laser head.
1.8 Electric safety
Warning : Don't use wet hand contact with any electrical
safety switch in order to avoid electric shock. Machine parts
with lightning signs, says these areas have high voltage
electrical appliances or electrical components, the operator
when close to these areas or open should take care all the
more, in order to avoid electric shock. For example, the
shield, machine tool servo motor position transformer
cabinets, electrical cabinet, etc.
Warning: I n the condition of electricity charged in don’t to
touch the electrical cabinet components, such as: CNC device,
servo device, transformer, fan, .etc.
